A case study of hospital contraceptive waste management practices in Chukwuemeka Odumegwu Ojukwu University Teaching Hospital, Awka, Anambra State

Background: Effective management of hospital waste is a critical component of a hospital’s infection control program and is central to occupational safety for healthcare workers. Thus, this study focused on the assessment of hospital contraceptive waste management practices at Chukwuemeka Odumegwu Ojukwu University Teaching Hospital (COOUTH) Awka, Anambra state, Nigeria. Methods: A cross sectional analytical study was carried out among healthcare workers selected using multistage sampling technique in 6 categories of healthcare workers in COOUTH. Data was collected using a pre-tested semi-structured interviewer-administered questionnaire and a World Health Organization (WHO) checklist and analyzed using statistical package for the social sciences (SPSS) version 22. Associations and correlations between variables were tested at the bivariate level using Chi-square and t-test. Results: A total of 86 healthcare workers were surveyed. The majority of the respondents were females, nurses with RN qualification. The mean knowledge score of the respondents was 94.8%. The attitude of healthcare workers towards segregation of hospital contraceptive waste at source point was 71% while the usage of gloves in handling hospital waste was 95.3%. The major factor affecting contraceptive waste management practices in the facility was the respondent’s cultural beliefs. The lack of funds to finance standard waste disposal methods was noted to be a significant barrier to optimum waste management practices. Conclusions: This study showed that despite the high level of knowledge of healthcare workers on hospital contraceptive waste management practice in COOUTH, the hospital contraceptive waste management practice is not functioning optimally in Anambra state. Hence, the need to reform the hospital waste management practice to achieve functional results.

Institutional Solid Waste Management Practices: Case Study of Agriculture University in Kashmir

This study was carried on solid waste management in Sher-Kashmir University of Agricultural Science and Technology Kashmir. It is noted that the advantages in managing solid waste at institutional level such as university because of its unique characteristics also influences the waste management needs and strategies. This paper outlines findings from a yearlong study through surveys, field investigations, including on-site waste measurements and questionnaire on institutional solid waste management. It was discovered that the waste's content was primarily organic in content, suggesting a strong disposing potential in terms of organic manure or biogas production through scientific digestion and composting. The study revealed that maximum contribution to organic waste in the form of food waste was from messes of the hostels (53.32 T). That can be biodegradable managed and properly disposed, hence make a significant change in the waste management system. Hostels also generate 17.77T of plastic waste annually that needs processing through scientific recycling techniques on sustainable basis. The study found that scientific segregation of trash might significantly improve solid waste management at other universities with a comparable environment.

Study of Municipal Solid Waste Management in Ranchi, Jharkhand

Solid waste management (SWM) have becomes a very serious concern globally. The lack of individual responsibilities as well as proper attitude and approach leads to this issue. Rapid industrialization, increase in population and further increase in standard of living and poor waste management have increased the serous health issue. In India we generate about one 1 lakh ton of MSW per day. Almost every ton of MSW is disposed of unscientifically. Though the compostable organic waste ranges between 34-70 percent, improper segregation or no segregation at source has challenged the further treatment and disposal experiments. Ranchi city need to be taken care by various new SWM techniques, proper management skill and adequate care the diseases and improve medical conditions. This paper deals with the proper description of the current MSWM process and the real time scenario where every individual is a source of waste creation. The effect of growing population of last ten years outcome of waste quality and quantity generated throughout these years have been discussed. It is observed that more than 4000 tons of waste per month is being generated. Researches shows that the disposal of solid waste requires 2,700,000 m2 area for the land up to the year 2030. Far sustainable development and effective management it is suggested that implementation of newer technologies, training of common people, and effective implementation of government policies will help to come out of these current issues

Modelo para estimativa da geração de resíduos sólidos domiciliares em centros urbanos a partir de variáveis socioeconômicas conjunturais / Model to domestic solid waste generation estimative in urban areas based on socioeconomic conjuncture variables

Este trabalho apresenta um modelo matemático para estimar a geração de resíduos sólidos residenciais urbanos. O modelo foi desenvolvido a partir de uma base física espacial de bairros de Belo Horizonte e dos indicadores socioeconômicos das respectivas populações, referentes ao período de janeiro de 2006 a dezembro de 2010. Verificou-se intrínseca relação entre a geração per capita de resíduos e a renda per capita nas regiões estudadas, testificada por coeficiente de determinação de 0,85. Posteriormente, efetuou-se a validação do modelo com dados da capital de Minas Gerais e de Porto Alegre, na qual os valores estimados foram confrontados com a geração real informada pelas prestadoras de serviços de limpeza urbana locais. A despeito de elaborado com dados de Belo Horizonte e aferido com os de Porto Alegre, os resultados abrem a perspectiva de emprego do modelo proposto na estimativa de geração de resíduos sólidos em áreas urbanas.

This work presents a mathematical model to estimate the solid waste generation in urban areas. The model was developed based on spatial physic basis of neighborhoods of Belo Horizonte and of the respective economic indicators of their population. A strong relation between per capita solid waste generation and per capita income was confirmed due the high coefficient of the determination 0.85. Afterwards the model was validated by means of Belo Horizonte and Porto Alegre datasets in which the estimated values were compared with the real solid waste generation provided by the local services. Despite of data set from Belo Horizonte, the results open the perspective of the application of the model for estimating the solid waste generation in urban areas.

Estimation of municipal solid waste generation and landfill area in Asian developing countries.

In developing Asian countries, the municipal cooperations are unable to handle the increasing amount of municipal solid waste, which into the uncollected waste being spread on roads and in other public areas leading to tremendous pollution and destruction of land and negative impact on human health. Generation of municipal solid waste increases with the rapid urbanization and accelerated economic development with in the rapidly growing advanced technological societies. The nature of municipal solid waste is a term usually applied to a heterogeneous collection group of waste produced in urban areas, the nature of which varies from region to region. The common problem faced by all developing Asian countries, is the disposal of municipal solid waste and availability of land fill site area. Present study explains the correlation analysis of among different factors of municipal solid waste and the objective is to assess the future municipal solid waste stream in Asian developing countries. The other goal of this study was to calculate the future land area that would be required for landfill site disposal in Asian developing countries.
